Electronic device having dual-lens element

Abstract

An electronic device includes a main body and a dual-lens element and the ability of the dual-lens element to capture stereoscopic or 3D images remains notwithstanding changes in orientation of the device. The dual-lens element is rotatable on a surface of the main body and includes a rotating disk, a dual-lens module, a gravity sensor, and a controller. The gravity sensor detects a rotation direction and a rotation angle of the main body when the main body is rotated relative to a horizontal plane and the controller controls the rotating disk to rotate about the rotation angle by way of compensation, thereby maintaining the horizontal aspect of the dual-lens module.

What is claimed is: 
     
       1. An electronic device comprising:
 a main body; 
 a dual-lens element rotatable on a surface of the main body, the dual-lens element comprising: 
 a rotating disk; and 
 a dual-lens module, the dual-lens module positioned on and rotatable on the rotating disk; and 
 a gravity sensor, the gravity sensor detecting a rotation direction and a rotation angle of the main body when the main body rotates the dual-lens relative to a horizontal plane; and 
 a controller receiving information about the detected rotation direction and the detected rotation angle, and controlling the rotating disk to rotate in an angle identical in degrees of angle and in a reverse direction of the detected rotation angle, thereby the dual-lens module remaining parallel to the horizontal plane. 
 
     
     
       2. The electronic device of  claim 1 , wherein the horizontal plane is perpendicular to gravity. 
     
     
       3. The electronic device of  claim 1 , wherein the dual-lens module comprises two lenses with the same size and shape, the two lenses are symmetrical to a center axis of the rotating disk. 
     
     
       4. The electronic device of  claim 1 , wherein the rotating disk comprises a disk body and a motor, the dual-lens module and the motor are positioned on opposite surfaces of the rotating disk. 
     
     
       5. The electronic device of  claim 4 , wherein the disk body is circular. 
     
     
       6. The electronic device of  claim 1 , the dual-lens element further comprising a cover, wherein the cover covers the disk body and the dual-lens module. 
     
     
       7. The electronic device of  claim 6 , wherein the cover is made from transparent plastics and glass. 
     
     
       8. The electronic device of  claim 6 , wherein the cover is circular. 
     
     
       9. The electronic device of  claim 1 , wherein the electronic device is a mobile phone. 
     
     
       10. The electronic device of  claim 9 , wherein the mobile phone is cuboid. 
     
     
       11. The electronic device of  claim 1 , wherein the electronic device is a tablet computer. 
     
     
       12. The electronic device of  claim 11 , wherein the tablet computer is cuboid. 
     
     
       13. The electronic device of  claim 1 , wherein the electronic device is an image capturing apparatus. 
     
     
       14. The electronic device of  claim 13 , wherein the image capturing apparatus is cuboid.
